Technical Field

[0001] The utility model relates to the technical field of distribution box equipment, in particular to a distribution box with a lifting and moisture-proof function. Background Art

[0002] The distribution box is a kind of electrical equipment and a very important power supply control center. Most of the existing distribution boxes are installed outdoors. When in use, most of the existing distribution boxes rely on the heat dissipation holes on the box body for passive heat dissipation. This type of heat dissipation efficiency is low, and it is easy for dust and moisture to enter. The box is humid, which is not conducive to the safety of the instruments and lines inside the distribution box.

[0003] After searching, the Chinese patent "Moisture-proof and Dehumidification Distribution Box" authorization announcement number "CN 214506199U" has multiple raised flat keys arranged in parallel to form an air supply channel, so that the wind from the cooling fan can reach the channel and be sent out from the ventilation holes along the channel, achieving a good heat dissipation effect. The setting of the dehumidifier plays a role in moisture-proof and dehumidification;

[0004] Although the above method can dissipate heat and dehumidify the distribution box, when it rains heavily, the air is humid and the dehumidification effect of the dehumidifier is limited, which will lead to poor moisture-proof performance of the distribution box and easy water accumulation on the installation surface, which will affect the operation of the distribution box. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-4 As shown, a distribution box with a lifting and moisture-proof function comprises:

[0025] A bottom frame 100, a top of the bottom frame 100 is fixedly connected to a protective eave 200, a bottom of the protective eave 200 is fixedly connected to an electric push rod 300, a bottom of the electric push rod 300 is fixedly connected to a box 400, and a humidity sensor 500 is arranged in the box 400;

[0026] The ventilation mechanism 600 includes an exhaust frame 610 arranged at the top of the box body 400, a fan 611 is arranged in the exhaust frame 610, a sealing cover 612 is arranged in the middle of the bottom end of the protective eaves 200, a controller 630 is arranged at the bottom end of the protective eaves 200, an air inlet frame 620 is arranged in the middle of the bottom end of the box body 400, two connecting plates 621 are arranged in the air inlet frame 620, and evenly distributed activated carbon plates 622 are arranged on opposite sides of the two connecting plates 621.

[0027] like Figure 4 As shown, the upper and lower activated carbon plates 622 are staggered, and the outer wall of the activated carbon plate 622 is fixedly connected to a blocking frame 623, and the opening diameter of the blocking frame 623 is consistent with the length of the activated carbon plate 622. The upper connecting plate 621 and the air inlet frame 620 are movably connected, and the lower connecting plate 621 and the inner wall of the air inlet frame 620 are fixedly connected.

[0028] A strip opening 110 is provided at the bottom end of the base frame 100, a cross bar 120 is fixedly connected to the inner wall of the strip opening 110, a round bar 121 is fixedly connected between the cross bar 120 and the upper connecting plate 621, and the round bar 121 is slidably connected to the lower connecting plate 621. The two lower connecting plates 621 cooperate with each other, the round bar 121 will ensure that the height position of the upper connecting plate 621 remains unchanged, and the lower connecting plate 621 will move upward synchronously with the air inlet frame 620, and the staggered activated carbon plates 622 and the corresponding blocking frames 623 cooperate with each other to achieve the blocking operation of the air inlet frame 620, thereby preventing the external humid air from affecting the operation of the device.

[0029] like Figure 4 As shown, a mounting plate 624 is fixedly connected to the upper opening of the air inlet frame 620, and a plurality of vents are provided at the top of the mounting plate 624. The mounting plate 624 can realize normal ventilation while installing the device, so that the two will not affect each other, ensuring the normal use of the device.

[0030] like Figure 2 and Figure 3 As shown, the inner top wall of the sealing cover 612 is provided with a sealing gasket 613, which is a rubber material component. When the exhaust frame 610 and the sealing cover 612 are attached, the sealing gasket 613 will block the gap between the two, thereby improving the sealing performance between the two.

[0031] Both sides of the inner wall of the exhaust frame 610 are provided with a clamping groove 614, a clamping block 615 is provided in the clamping groove 614, and a filter plate 616 is fixedly connected between the two clamping blocks 615. The filter plate 616 can prevent foreign impurities from entering the box body 400 from the exhaust frame 610. At the same time, the setting of the clamping block 615 and the clamping groove 614 can realize the disassembly of the filter plate 616, which is convenient for the maintenance of the filter plate 616 in the later stage.

[0032] like Figure 1 As shown, the shape of the protective eaves 200 is eaves-shaped, and evenly distributed guide grooves 210 are provided at the top of the protective eaves 200. The cooperation of the eaves-shaped protective eaves 200 and the guide grooves 210 can guide rainwater falling on the top of the protective eaves 200 to prevent rainwater from entering the box body 400 from the exhaust frame 610.

[0033] Working principle: When the device is in normal use, the fan 611 is started. Under the guidance of the airflow, the external gas enters the air inlet frame 620 from the lower strip port 110. The air is filtered by the activated carbon plate 622 in the air inlet frame 620 and enters the box body 400. Under the guidance of the fan 611, the gas in the box body 400 passes through the exhaust frame 610 and is discharged into the air, realizing the air replacement of the device and achieving the purpose of ventilation and heat dissipation of the device. When the humidity sensor 500 in the box body 400 detects that the humidity is too high, the data is transmitted to the controller 630, and the controller 630 starts the electric push rod 300. The electric push rod 300 drives the box body 400 to move upward to realize the lifting operation of the box body 400. The positions of the protective eaves 200 and the sealing cover 612 remain unchanged, and the exhaust frame 610 enters into the sealing cover 612 to realize the sealing operation of the upper exhaust frame 610. The two connecting plates 621 below cooperate with each other. The height position of the upper connecting plate 621 remains unchanged, and the lower connecting plate 621 will move upward synchronously with the air inlet frame 620. The staggered activated carbon plates 622 and the corresponding sealing frames 623 cooperate with each other to realize the sealing operation of the air inlet frame 620, thereby preventing external humid air from affecting the operation of the device.

[0034] It should be noted that the electric push rod 300, humidity sensor 500, fan 611, controller 630, etc. in the above description are all devices with relatively mature application of existing technologies. The specific models can be selected according to actual needs. At the same time, the electric push rod 300, humidity sensor 500, fan 611, and controller 630 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation. The value of the humidity sensor 500 can be set according to the specific situation. At the same time, the humidity sensor 500, the electric push rod 300 and the controller 630 are used in conjunction with each other, and are technical means known in the field, which will not be elaborated here.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
